Patent number: 5773112Abstract: A label with a metallic layer of controlled thickness comprising a transparent or semi-transparent film, a metallic layer which is formed by metal deposition, has a light transmittance of 3 to 70%, and is formed on one side of the film, and a layer of an adhesive material formed on the metallic layer. Alternatively, a protective layer may be formed on the metallic layer, and the layer of an adhesive material formed on the other side of the film. The label is transparent even though it shows metallic gloss, has remarkably beautiful appearance, and is suitable for artistic design.Type: GrantFiled: January 2, 1997Date of Patent: June 30, 1998Assignee: Lintec CorporationInventors: Kohei Tachikawa, Akira Katayama, Toshio Minagawa, Shigenobu Maruoka

Patent number: 5683805Abstract: Described is a colored film formed of a transparent film and at least one colored adhesive layer arranged on one side of the transparent film. The adhesive layer has been colored by a colorant composed of a pigment and a dispersant. The dispersant comprises a (meth)acrylate ester polymer formed, as essential monomer components, of an aromatic vinyl monomer, a primary to tertiary amino-containing (meth)acrylate ester monomer and a (meth)acrylate ester monomer containing an ammonium group quaternized with an aromatic compound.Type: GrantFiled: March 15, 1996Date of Patent: November 4, 1997Assignee: Lintec CorporationInventors: Katsuyuki Oita, Kohei Tachikawa, Leonardo M. Garcia, Chandrakant C. Patel, Toshio Minagawa

Patent number: 5064064Abstract: A cover tape for sealing chips in chip-holding parts of a carrier tape having said parts provided discontinuously and longitudinally of said carrier tape, which cover tape comprises a base tape, an adhesive layer formed on one surface of said base tape and a non-adhesive coat formed on said adhesive layer along the longitudinal direction of said base tape so that said non-adhesive coat has a width broader than that of the chips and narrower than that of said adhesive layer. When the cover tape is used in combination with the carrier tape, the chip-holding parts are sealed by the cover tape having the non-adhesive coat and in consequence the chips held in the chip-holding parts do not come in contact with the adhesive layer although they might come in contact with the non-adhesive coat. Accordingly, the chips are not stained by the adhesive in the adhesive layer.Type: GrantFiled: November 6, 1990Date of Patent: November 12, 1991Assignee: Lintec CorporationInventors: Kazumi Itou, Kazuyoshi Gbe, Toshio Minagawa

Patent number: 4994300Abstract: A cover tape for sealing chips in chip-holding parts of a carrier tape having said parts provided intermittently and longitudinally of said carrier tape, which cover is constituted by a base tape, an adhesive layer formed on one surface of said base tape and a non-adhesive coat formed on said adhesive along the longitudinal direction of said base tape so that said non-adhesive coat has a width greater than that of the chips and less than that of said adhesive layer. When the cover tape is used in combination with the carrier tape, the chip-holding parts are sealed by the cover tape having the non-adhesive coat and in consequence the chips held in the chip-holding parts do not come in contact with the adhesive layer although they might come in contact with the non-adhesive coat. Accordingly, the chips are not stained by the adhesive in the adhesive layer.Type: GrantFiled: December 7, 1989Date of Patent: February 19, 1991Assignee: Lintec CorporationInventors: Kazumi Itou, Kazuyoshi Ebe, Toshio Minagawa
